Iments for Boats, of which the followingis a specification. Y

My invention is an improvement in that class of propellers which areadapted to be detachably connected with boats and suspended in the waterat the stern.

My invention includes novel and improved features, as hereinafter setforth and claimed, the same being illustrated in the accompanyingdrawings, in which- Figure 1 is a longitudinal section of my improvedapparatus or propeller attachment arranged in the position for use, theoutline of the stern of a boat being shown by dotted lines. Fig. 2 is aside view, inreduced proportions, showing the same apparatus in thefolded position as when detached from the boat. Fig. 3 is a viewillustrating details of construction by which the two hinged portions ofthe apparatus are rigidly secured to each other when the propeller is inworking position. Fig. 4 is a plan view of the apparatus or attachmentin working position.

Fig. 5 is a transverse section on the line 5 5 of Fig, 4. Fig. 6 isaperspective View of one of the adjustable bars by which the horizontalportion or platform of the apparatusv is secured upon the deck and sternof a boat. Fig. 7 is a perspective view, including the rear portion ofthe platform, adapted to be secured upon the stern of a boat, togetherwith the driving-shaft and its bearing.` Fig. 8 is a perspective view ofthe rigid bracket or frame in which the 4propelling mechanism proper isarranged and supported. Fig. 9 is an renlarged horizontal section on theline 9 9 of Fig. 1. Fig. 10 is a vertical section of the rearsteering-wheel, parts for locking the same and the propeller in anydesired position being illustrated in side view.

As shown in Figs. 1, 2, and 4, indicates a rectangular metal platform orframe adapted to be placed and supported upon the rear or stern portionof a boat, B a frame carrying the propelling mechanism roperV and havinga hinged connection Wit said platform A, but provided with means forsecurit in vertical positiomas in Figs. l and 4 and as required for`propulslon.

I will now proceed to describe the details of construction, arrangement,and operation of the parts A and B, together with those attachedthereto. The platform A rests horizontally u on the stern-deck of a boator upon the ffameworkvthereof and is secured in place mainly by means oftwo bars 1, (see Figs. 4, 5, 6,) Which are arranged transversely beneaththe platform A in suitable guides or keepers 2, in which they may beclamped by means of screws 3. The outer ends of the bars 1 are curved toform what may be termed goosenecks 4 andprovided with clamp-screws 5.vIn practice these bars are drawn out and the goosenecks 4 applied to thegunwales or side ledges of the boat or to other fixed portions of thelatter and clamped by the screws 5. Screws 3 being then also tightened,the platform will be secured rigid y in the required position with itssides equidistant from the sides of the boat.

The part B, in which the propelling mechanism is sup orted and has itsbearings, comarts, which have a rises the ollowing inged connection witthe platform A at a, 1, by means of a broad bracket or arm 6: Theropeller 7 is mountedl upon a horizontal s aft 8, having a bevel-gear 9,which meshes with a corresponding one, 9a, keyed upon a vertical shaft10, which is driven from the horizontal shaft 11, having its bearings ina box 12, secured upon the platform A. Thel base of the bearing 12 (seeFig. 7) may be solidly constructed and the upper portion thereofconstructed as a cap 12a, the driving-shaft 11 having a series ofcollars 11, running in suitable grooves in the respective parts 12 12a.-An oil-box 13 is provided in the upper portion of the bearin andcommunicates with theshaft and col ars by suitable ducts, as shown.shaft 11 is communicated thereto by any suitable means or motor, thesame being arranged on the latformAor otherwise, as conditions and 1ndment may dictate. -The driven shaft 10 as its' upper bearing in a tube13, which is fixed in the four-armed bracket or frame.. (Illustrated inFi i. 8.) Such bracket and the tube 13 ,before re erred to,constitutethe main portions'of the hinged part lB. The tube 13 is heldin the upper ring 14 of the bracket, and the curved arm 15 of the latteris provrded at its lower end with a smaller ring 16, which is alinedwith the upy er one, 14. The lower ring 16 constitutes a earin for ahollow rotary shaft 17, the upper en of the same projecting into thelower roo4 IIC.

vss

portion of the fixed tube 13 and provided with antifriction-bearings, aswill now be described. Thus the rotatable tube 17 is provided with ahorizontal flange 18, which is inclosed in a circular box land arrangedbetween antifriction-balls, as shown in Fig. 1. The said box is formedby enlarging the lower end of the tube 13 and providing it With apendent internally-threaded flange into which the vertical flan e of ashort tube 19 is screwed, as shown. y this arrangement anantifriction-support is obviously grovided for the rotary shaft 17. nantiiction-bearing, whereby it is held in vertical position, is furtherprovided by means of rollers 20, (see Fig. 9,) having their bearings inthe sides of theixed tube 13 and the removable short tube 19. In otherwords, the rollers 20 work in contact with the side of the shaft 17,being held rotatably in recesses provided in the parts 13 and 19. Theshaft 17 is connected with a horizontal bearing 21, which constitutes abearing for the propeller-shaft 8. The latter is provided with acollar21, abutting a sleeve 22, whose inner threaded end is screwed intothe adjacent internallythreaded tubular portion of the bearing 21.

By this means the gear 9 of the propellershaft 8 is held duly engagedwith the gear 9@l of the driving-shaft 10. It is obvious that this meansprovides for taking up wear at any time, so that the ears are held dulyin mesh. To further provide for a nice adjustment of thepropeller-shaft, I arrange a set-screw 23 in the inner solid portion ofthe bearing 21, the same abutting the inner end of the said shaft. Theouter bearing of the shaft is rovided by a collar 24 and a cap 25, whicis threaded internally to adapt it to be screwed on the tubular nut '22and also incloses the said collar 24. By this means I provide for suchadjustment of the bearing as may be required from time to time. Beneaththe propeller7 I arrange a guard-plate 26, whose inner end is kprovi edwith a screw-stem 27, by which it 1s secured in the lower pendenttubular portion of the bearing 21.

It is apparent that by applying power to the driving-shaft 11 thevertical shaft 10 will be driven correspondingly and the propeller 7thereby rotated with like speed, provided the meshing gears be of likesize as in this case. justed in line with the axis of the boat, thepropulsive effect will obviously be applied in the same direction; butby means of the rotatable shaft 17 and the bearings therefor lic-- vforedescribed the propeller may be shifted around the axis 10 at anyrequired angle for guidin the boat in different directions, so that w endesired the function of a rudder is performed by the propeller inaddition to its ordinary function. For adjusting such shaft 17andthereby placing the propeller at dil'- ferent angles, as may berequired, l employ Assumln that the bearing 21 be ad-v the followingmeans:` A vertical shaft 28 is arranged in bearings 29 (see Fig. 8) ofthe curved portion or yoke 15 of frame B and provided at the top with asteering-wheel 30 and near its lower end with a gear 31, that mesheswith a correspondin gear 32, keyed upon the hollow shaft 17 an arrangedabove the lower ring 16 of the frame B. It is apparent that by rotatingthe shaft 28 through the medium of the steering-wheel 30 the shaft 17may be rotated while the propeller 7 is at rest or in motion for settingthe propeller at any angle to the axis of the boat as may be requiredfor steering the latter in any direction. A foot-platform 33 (see Figs.1 and 4) .is provided for the steersman, the same being rigidly attachedto and supported by the tube 13. In other words, said foot-platform 33forms a rigid attachment of the hinged portion B of the apparatus.` Inconnection with the steering-wheel and the shaft 28 I provide means forlocking them in any required position, so that the propeller 7 may beset at any required position and then locked in said position. As arule. the lock will be applied for lholding the pro eller with its shaftin line with the axis of t e boat, in which case supplemental steeringmechanism will be utilized. The locking means are as follows:Aratchet-collar 34 is secured upon a fixed support of the platform 33,and a lever 35 is pivoted to an arm pendent from the steering-wheel 30.A spiral spring 36 presses the inner end of said lever into engagementwith the ratchet 34, and a push-bar having a head 37 is attached to theother end of tlie lever, so that by depressing it the steeringwheel andshaft 28 are unlocked.

I provide a supplemental and manuallyoperated steering mechanism, thesame consisting of a rudder 38, (see Fig. 1,) having a vertical shaft39, which -is pivotally attached at 40 to the yoke 15 of frame B and'provided at its upper end with a cross-bar 41, from which cords or wires42 extend forward through guides 43 on the platform A to the shaft 44 ofa hand steering-wheel 45, the said shaft having its bearing in asuitable bracket 46, forming an attachment of the front end of theplatform. It is apparent that by rotating the wheel 45 a boat may besteered by means of the rudder 38 without recourse to thepropelleradjusting mechanism before described, and, on the other hand,if the rudder be left free-the boat may be steered by means of thepropeller, as described.

position, 'as shown in Figs. 1, 3, coincidin with holes in vertical lugs47, forming rigi portions or attachments of the rear end of the platformA. Clamp-screws 48. passing through the coincident openings of the parts15a and 47, serve to secure the frame B and its attachments in thevertical working position. (Indicated in Figs. 1 and 4.) By removingsuch fastenings 48 the whole hinged portion of the apparatus may beswung on the hinge a in the position beneath the platform andpractically parallel thereto. words, the part B and all its attachmentsmay be folded together with the platform A when detached from a boat, sothat the same will occupy a minimum space, as required fortransportation or storage. For securing the parts in the folded positiona strap 49 may be passed under the hollow shaft 17 and through slotsprovided in lugs 50, that are pendent from the side edges and frontportion of the platform A. When the part B and its attachments are thusfolded, the transverse bars 1, by which the platform is vsecured to theboat, are drawn out of the keepers 2 and inserted in keepers 2, (seeFig. 1,) so that they are held longitudinally parallel to the platforminstead of being transverse thereto.
